  • package inject

    Play's runtime dependency injection abstraction.

    Play's runtime dependency injection abstraction.

    Play's runtime dependency injection support is built on JSR-330, which provides a specification for declaring how dependencies get wired to components. JSR-330 however does not address how components are provided to or located by a DI container. Play's API seeks to address this in a DI container agnostic way.

    The reason for providing this abstraction is so that Play, the modules it provides, and third party modules can all express their bindings in a way that is not specific to any one DI container.

    Components are bound in the DI container. Each binding is identified by a BindingKey, which is typically an interface that the component implements, and may be optionally qualified by a JSR-330 qualifier annotation. A binding key is bound to a BindingTarget, which describes how the implementation of the interface that the binding key represents is constructed or provided. Bindings may also be scoped using JSR-330 scope annotations.

    Bindings are provided by instances of Module.

    Out of the box, Play provides an implementation of this abstraction using Guice.

  1. implicit val NoMarker: MarkerContext

    A MarkerContext that returns None.

    A MarkerContext that returns None. This is used as the "default" marker context if no implicit MarkerContext is found in local scope (meaning there is nothing defined through import or "implicit val").

    Definition Classes
    LowPriorityMarkerContextImplicits
  2. def apply(marker: Marker): MarkerContext

    Provides an instance of a MarkerContext from a Marker.

    Provides an instance of a MarkerContext from a Marker. The explicit form is useful when you want to explicitly tag a log message with a particular Marker and you already have a Marker in implicit scope.

    implicit val implicitContext: MarkerContext = ...
val explicitContext: MarkerContext = MarkerContext(MarkerFactory.getMarker("EXPLICITMARKER"))

// do not use the implicit MarkerContext
log.error("This message is logged with EXPLICITMARKER")(explicitContext)
    marker

    the marker to wrap in DefaultMarkerContext

    returns

    an instance of DefaultMarkerContext.

  3. implicit def markerToMarkerContext(marker: Marker): MarkerContext

    Enables conversion from a marker to a MarkerContext:

    Enables conversion from a marker to a MarkerContext:

    val mc: MarkerContext = MarkerFactory.getMarker("SOMEMARKER")
    marker

    the SLF4J marker to convert

    returns

    the result of MarkerContext.apply(marker)
